Deflection Of Cantilever Beam Lab Report

The specimen ends were not thick or had moving wedge grips to keep it secure in the holders of the servo-hydraulic load frame. The movement of the specimen in the machine causes some of the data to be an inaccuracy. Also, the transverse strain causes issues with the strain gages that are called transverse sensitivity. The transverse sensitivity affects the accuracy of the data that is being collected for the transverse strain more than the longitudinal strain. This is greatly seen in the percent difference in the strain values such as in one case the Longitudinal strain was .4% while the transverse strain was 30%. Another issue with the strain gages was that if the strain gages weren’t properly placed on the specimen the data accuracy would

In the past few years prototype has been going under many modifications. Last year it was completed but few flaws were there. Spring Mechanism was used by previous degree but it was not reliable as due to excess use spring lost its elasticity and could not be used for triggering. Spring mechanism was also not aesthetically good. A lot of aesthetics was to be done. To cater for this problem we used limit switch for efficient triggering and made compact circuitry using 8 pin controllers and added much to aesthetics of limb.

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

Continuing with the development and improvement of the assembly line, in the 1960s, new machines were invented that allowed for five axes of motion. These devices were called the “Versatran”, and were installed a Ford factory in Ohio. But later in the decade, robots became even more complex adding another axis it can work

The Love-Kirchhoff hypothesis generalises the plane section assumption in beam theory; assuming the normal to the laminate remains normal to the deformed laminate and the normal undergoes no extension of shortening. Leading to:

In the article, “National Anthem Protests”, written by Steve Byas on The New American, on October 24, 2016, states that when the San Francisco 49ers backup quarterback, Colin Kaepernick, decided to kneel during the national anthem that his protest wasn’t about the police brutality on blacks but to disrespect this country. Texas senator, Ted Cruz, states in the article that “it’s very easy when you’re sitting there, rolling in millions of dollars to disrespect this country” (13 Byas). Kaepernick and many other NFL players have stated that they are not disrespecting our flag but kneeling in protest to the police brutality on black people across the country. Although the players have said this, people beg to differ.

Students in an AP Physics lab perform an electrostatics experiment involving two charged spheres suspended

Adding additional uplift capacity to the stringers while minimizing changes to the beam cross section will be essential to preventing future damage to the stringers

This report has been written to describe an experiment performed on a channel section examining the stiffness of the beam through two differing types of deformation – curvature and deflection. The aim of the experiment was to determine the value of the flexural rigidity (EI) in two different ways; using the curvature, k, and the mid-span deflection. The testing method used for the experiment is described. The experiment found that the EI values calculated were as follows: - EIcurv = 1.76E+10 Mpa.mm4 when calculated using the curvature, k. - EIdefl

In this experiment we tested the effect of change in arm length of the Trebuchet on the distance traveled of the projectile. We wanted to do this experiment due to our interests in engineering and our interests in the medieval era siege weaponry. We started by researching different types of Trebuchets and decided to go with the most modular and modern version. We decided to build a floating arm Trebuchet which uses the counterweight as the fulcrum. This allowed us to easily exchange the arms for testing. We built the Trebuchet using long 5.08cm x 10.16cm (2in x 4in) pieces of wood, four 4.54kg (10lb) weights, a single 1.27cm (1/2in) x 1.22m (4ft) piece of rebar, and a pouch made of paracord and duct tap. We tested this by building a Trebuchet

An object that has rotational equilibrium, or is balances, has a net torque of 0. The torque of an object is directly proportional to the distance from the applied force to the pivot point, the applied force and its angle; and the formula is T=F*d*sinθ. In this laboratory, we unbalanced and balanced a meter stick by hanging different masses from different distance of the pivot point. In addition, the mass of the meter stick was found using the torque formula.

Note: the new design is to prevent the bottom face of the beam from bending and further weakening the

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.

The objective of this experiment is to demonstrate the bending of a bean when loaded at the center of its length and examine its deflection when positioned in two different ways, when the flat side of the beam is support and when the thin side is supported. In addition, try to find linear relationship between the load applied and the deflection of the beam and comparing the experimental deflection with the theoretical deflection.

- It will act as a force that will completely neutralize F4. The force F4 and the resultant of F1, F2, F3 are exactly opposite of each other.
